IMPROVEMENT IN EENCES.

v'.ll'he Schedule referred to in these Letters Patent and making part of the lame.

To all 'whom this may concern Be it known that I, JAMES T. DBUMMOND, of

Mount Pleasant, in the county of' Henry and State of Iowa, have invented an Improved Fence and I do hereby declare that the following is a full, clear, and

The'present invention relates to the novel construc-l tion and arrangement of locks for holding removable .panelsfirmly in the fence, and holding the lengths in position when they run over undulated ground, as the' whole is hereinafter fully described.

L" L L represent the several panels of the fence, and R S T U the horizontal boards or rails of which, together with the vertical battens H, they are formed, said boards or rails being secured to the batteus-by means ot' nails or otherwise, as most convenient.

As will be seen in drawing 1, the two middle rails or boards of the panels are shorter than the bottom and top rails, by which means the rails R bear in the notches on Ithe tops of thetrestles, and the rails U t in-to the notches made in the under sides of the crossties E; c

To arrange the panels so that any one of lthem can 'be removed, the middle rails S T in panel Lare thus form a passage-way or a commencement for taking down the fence preparatoryv to its removal.

In order to form a secure fastening for the said panel L' when in position to form a part of the fence, a lock, N,=is pivoted to thetrestle A, and its top ends have such a width that-when it is placed between the end hatten ,H and said trestles the panel will be held fast, the top of the lock being provided with a notch to allow it to go past the top end of the trestle, as shown in iig. 1.

The panels'L L" are represented as passing over an elevation of the ground; and in such a case, to hold the upper .parts of the panels fast, a pivoted wedge,- T', is so arranged as to iit between the panel and trestle, and consequently ll the angle caused by the uneven ground. When the nature of the ground requires it, similar wedges may be used at the bottoms of the panelsfor the same purpose.

The method of securing the angles of the fence consists in making the central rails at that part the longest and keying them to the battens ofthe adjoining panel.

In the foregoing I have described and shown a complete fence; but I do not claim to have originated the panels nox` trestles, but have shown them, to enable others to use the locks or wedges.

C' laim.

I claim- The locks or wedges N T', arranged to hold removable panels in place and support the panels of the fence running over undnlated ground, as setvforth'.
